In recent years, with the rapid development of the economy, my country's paper industry has continued to develop at a high speed. In 2004, there were about 3,500 paper and paperboard production enterprises in my country. The paper and paperboard production volume was 49.5 million tons, the consumption volume was 54.39 million tons, and the per capita annual consumption was 42kg, production and consumption accounted for 10% and 14% of the world's total, second only to the United States. The development of the paper industry not only satisfies people's growing material and cultural needs, but is also an important part of my country's import and export trade. However, the development of the paper industry also consumes a lot of energy, which has caused a series of environmental problems. The increasing shortage of resources and the deteriorating environment have become important factors restricting the development of my country's paper industry. Waste paper (WP, also known as secondary fiber) is a very important recyclable resource. Full use of it can not only save a lot of plant fiber raw materials, energy and reduce costs, but also reduce solid waste emissions. , Protecting the environment, not only has good economic benefits, but also has good social and environmental benefits.
The waste paper baler is an important link in the recycling of waste paper, which is of great significance to the utilization of easily compressible renewable resources such as waste paper. At the same time, my country's waste paper recycling rate is relatively low and needs to be further improved. This also shows that the application of waste paper baler is very necessary and requires further promotion and research.
In the mid-1970s, hydraulic baling presses began mass production and put into use. In the 1980s, large-tonnage hydraulic balers were also put into use, and my country's waste paper processing technology and technology took a new leap, and the quality of waste paper packaging was comprehensively improved. Practice has proved that the hydraulic baler has compact structure, flexible operation, high degree of automation, long service life, large pressure tonnage, and greatly improved waste paper density. It saves packaging materials and reduces the loss of vehicle transportation. The economic benefits are considerable. However, the hydraulic baler has the problem of inferior quality of hydraulic parts, and at the same time requires maintenance and technical quality of the operator.
